Memory seat, problem

Hello, today I have found a problem with the driver memory seat. I am not able to save any position. I think I do not do anything wrong, I get into the car, turn the clasp into the first position (motor does not run). Place the seat, outside and inside mirror as I should like to have it, print set and then for 1 second e.g. 1. After I move with the seat, but after printing from 1 it does not come back… Do I do something wrong? o as with the seats limp everything runs without problems…
